# Viant

Use GrowthLoop audiences for Viant DSP segment membership.

Connect this destination to export audience membership onto a Viant DSP segment, for use in Viant campaigns.

This destination writes to your Viant account and is a good fit when you want to:

* Make **GrowthLoop audiences** available for Viant DSP campaigns
* Match contacts on email
* Have a Viant **Segment Name** and **Segment ID** for the export

This maps to GrowthLoop Audiences:

| Use it for                                                   | Audiences |

# Prerequisites

Make sure you have:

* A Viant DSP account. See [Viant](https://www.viantinc.com/) if you need one.
* **Username** and **Password** partner credentials for GrowthLoop. Ask your Viant representative. These are not your regular Viant login.
* The **Segment Name** and **Segment ID** you will send membership to.

# Set up Viant as a destination

1. In GrowthLoop, click the **Destinations** tab on the left sidebar.
2. Click **New Destination** in the top right corner.
3. Search for **Viant** and click **Add Viant**.
4. Enter the required information, then click **Create**.

| Field                | Description                                                                                                            |
| -------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| **Destination Name** | Name this destination in GrowthLoop. Use a name so your team recognizes its purpose, like "Viant DSP".                 |
| **Sync Frequency**   | Set the default export frequency (for example, daily or weekly). You can override this setting for individual exports. |
| **Username**         | Partner username from your Viant representative.                                                                       |

> ⚠️ Warning
>
> Use the GrowthLoop partner credentials your Viant representative provides. Do not paste a regular Viant user login.

**Viant** then appears in your list of connected destinations.

# Export to Viant

# Export behavior

This is what GrowthLoop writes when you export an audience.

| Behavior                   | What happens                                                                                                                   |
| -------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| **What GrowthLoop writes** | Membership on the Viant segment you named. Direction is GrowthLoop → Viant.                                                    |
| **When it runs**           | GrowthLoop sends the export as a batch on the next successful run. An export that starts **Now** runs within about 15 minutes. |
| **Segment**                | GrowthLoop sends rows to the **Segment Name** and **Segment ID** you entered.                                                  |
| **Match field**            | Email, hashed as SHA-256. Additional mapped identifiers are included on the row.                                               |
| **Add**                    | GrowthLoop inserts hashed identifiers into that segment.                                                                       |
| **One-time exports**       | GrowthLoop sends current membership once.                                                                                      |
| **Ongoing exports**        | Ongoing exports add contacts who enter the audience. Viant exports do not support removals.                                    |
| **Deletes**                | GrowthLoop does not delete the Viant segment. Contacts who leave the GrowthLoop audience stay on the segment.                  |

# Confirm the export was successful

When the run finishes, confirm you can use the data in Viant.

* **Audience export:** Sign in to Viant, open **Identity Management**, and look up the **Segment Name** you entered.
